Nvidia kept us waiting anxiously this morning to see what their mysterious announcement turned out to be. On Friday, the graphics card maker tweeted, "ARE YOU READY? Check back here on Monday morning at 9:00 a.m. PST for a major announcement!"

Turns out the announcement will keep us waiting even longer. According to another Tweet posted by Nvidia, "The wait is almost over! The world's fastest PC graphics gaming technology will be unveiled at PAX 2010."

If you are lucky enough to attend PAX East 2010 in Boston, Massachusetts on March 26th, you can test out Nvidia's next generation GPU, and according to Nvidia's website, possibly purchase one before anyone else.
